I could use some help with my Wild Western. It is totally dead, with nothing coming up on the screen and no sounds. I've replaced the power supply with a new switching power supply from arcade shop (the original was dead) and verified that the monitor shows a picture. Araknoid looks great by the way with Wild Western train tracks running through it.
Gonna replace that monitor as soon as I get this thing running.
Anyway, I'm pretty sure the board is dead. I've verified that when powered it's got 5 volts going through the chips, but I still get absolutely nothing on the monitor or through the speakers.
I took the board out yesterday to clean and inspect it. First thing I noticed is that many of the chip legs were very very corroded. I did what I could to clean them up with a toothbrush and water. See before and after:
Otherwise, the board looks like it hasn't been touched in 30 years. I see no signs of abuse. There are no scratched traces or bad soldier joints. The only other issue I see is possibly this chip:
Does this look toasted? How would I go about debugging/fixing it?
